Please find in attachment the following four files: apt.dat : it contains our apt measurements (HJD, V, B-V, U-B) fading.dat: it contains the measurements during fading events runoff.dat: it contais the epochs when our apt could not find the star, because its brigtness was presumably below the detection threshold v.dat : the complete collection of Hipparcos and apt V magnitudes. I will appreciate very much to be informed on the results of your research.
